Description

Technical Field

[0002] The welding fixture is used to ensure the size of the weldment, improve assembly accuracy and efficiency, and prevent welding deformation. The general welding fixture is composed of an upper fixture and a lower fixture. The upper fixture and the lower fixture are used to clamp the weldment so that the weldment can be welded stably. Figure 7 When welding is performed as shown in the figure, three welding plates need to be combined together to form a C-shaped structure, so three clamp plates are needed to clamp and fix the three welding plates.

[0003] The existing welding fixture generally has a locking mechanism that is locked by bolts and threaded holes, and the bolts and threaded holes are threadedly connected to fix the fixture plate. The fixture plate needs to be disassembled and maintained or replaced regularly during use, mainly to ensure that the fixture plate can effectively clamp the welding workpiece. The fixture plate may deform during long-term use. Once the fixture plate is deformed, a gap will appear between the fixture plate and the workpiece, which will make the welding workpiece unable to be effectively clamped. However, this connection method usually requires at least two bolts to fix the fixture plate when installing it, and the bolts need to be removed multiple times to complete the disassembly of the fixture plate during disassembly, which leads to a long time for disassembly and installation of the fixture plate.
